WINDMILL.

SPECIFICATION forming part of Letters Patent No. 278,756, dated June 5,1883.

Application filed July 1l, 1882.

(No model.)

To all whom, it may concern: v

Beit known that I, NVARREN J. VAUGHN, a citizen of the United States,residing at-Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Windmills; vand Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part o f this specification.

My invention relates to Aimprovements in windmills, and the objects ofmy improvements are, first, simplicity of construction; second,cheapness, third, greater power accordmg to size and cost; fourth,durability; fifth, ease of regulation; sixth, securing the mill from thedanger of being blown off the tower.

in case of violent wind-storms, which seems the chief trouble with allother mills that have been tried. I attain these objects by themechanism illustrated in the accompanying drawings, in which- Figure lis a representation of the entire windmill when in operation. Fig. 2 isarear view, looking onto back of mill, showing fanframe, hinges, andconnections. Fig. 3 is an enlarged view of fan-hinge and end of one ofthe fan-arms detached. Fig. l:tis aview of the working parts of themachine with the flywheel removed. Fig. 5 shows the entire mill when atrest with the rope or wire C pulled down and fastened, allowing thefan-leaves 7L to be thrown into such a position as to offer noresistance to the wind, as is the reverse when the rope or wire C isloosened, shown in Fig. l,..and by the weight g on the regulating-leverD causes it to drop, and a consequent elevation of the fan-frame, whichcoming in contact with H, the fan-leaves are presented to the wind andmotion is obtained.

Similar letters referto similar parts throughout the several views. Y

A represents the tower and table on which the turning frame B rests, andthey are connected bya hollow spindle, b, passing through thetower-table A and secured by the nut ay underneath.

B is the turning frame, (shown more clearly n- Fig. 4,) which turns onlyas the wind changes. l

C is the power-shaft, with which E and H are connected. frame B, and,through the gear wheels ff, transmits thc power to the vertical powerina slot in the top ofthe turning frame B, and having its end forked tofit into a groove in the frame into or out of gear, accordingly as it islowered, as represented in Fig. l, or raised, as in Fig. 5, which isdone by means of v rope c being fastened or loosened. As a violentwind-storm increases in velocity its only tendency is to throw this millout of gear, while the revolutions would remain the same, and even anytrouble from that source is anticipated and neutralized by regulatingthe position of the weight r/,which is easily moved back and forth onthe regulating-lever D, and may be locked in position by a thumb-screwon it.

` E is the ian-frame, with connections with H by hinges fi, to which thefans 7L are attached, so that when the fork end of the regulating-leveris lowered, the fork fitting into the groove in the fan-frame E, whichslides on shaft C, as seen in Fig. 4, it pulls down the frame E, whichthrows the fans into a position of non-resistance to the wind, andconsequently out of gear, as in Fig. 5.

H is a frame similar to E in construct-ion. It is immovably attached tothe end of the power-shalt C', and has the fan-hinges 'L' attached tothe ends of its arms, as shown in Fig. 2.

c is a rope or wire passing up through the hollowlvvertical shaft b,passing on both sides ofthe ineliiredpower-shaft C, and connects withthe regulating-lever D. It is used to raise or lower the forked end of Din order to throw the mill into or out of gear.

e are rollers or wheels which assist and steady the movements of theturning frame B and prevent jarring or shaking.

The fan-leaves h are made somewhat concave to catch the wind more thanwhen entirely flat, and they are connected to the frame H by the hingesi.

It passes through the arm of D is the regulating-lever, resting on abolt fan-frame E, for the purpose of throwing the,

IOO

The frame E slides along -the shaft C, while frame H is immovablyattached to the end of the same shaft.

Prior to my invention all or nearly all windy mills have been operatedon a turn-table, or its equivalent, and have been thrown to the wind bymeans of a vane or fan-tail. In the case of my improvement there is novane or tail; but the operation is so easy and simple that it becomesself-adjusting. In other windmills the turn-table turns. In mine it doesnot, being fast to the tower, and the frame B alone turns. In othermills the fan-leaves are immovable, except in their revolution. In mine,besides the revolution, the attachments E and II, but more particularlyE, by the aid of the hinges '5, can be given the wing motion by means ofthe adjustable rope or wire c, and it matters not whether the mill is inoperation.

The entire mill is constructed of metal, eX- cepting the tower, which,for protection from prairie and other fires, may be constructed ot?metal also. Y Having thus described my invention, what I claim thereinas new, and desire to secure by Letters Patent, is-

l. In a windmill, .the combination, with a turning frame, B, a power-shaft passing through one of the sides of said frame, a pivotedregulating -lever provided with an adjustable weight, the inner end ofsaid lever being split to grasp a collar or rim on said shaft, of thetower-table A, around which the frame B turns through the interventionof the friction-rollers e e, substantially as and for the purpose setforth.

2. In a windmill, the combination, with the tower-frame A, of theturning frame B, powershaft, and hollow rope-shaft b, the power-shaftbeing provided with a weighted lever, as described, and the framesconnected by hinged plates fi, arranged and actuating substantially asand -for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
